chips is an Xorg driver for Chips and Technologies video processors.
The majority of the Chips and Technologies chipsets are supported by this
driver. In general the limitation on the capabilities of this driver are
determined by the chipset on which it is run. Where possible, this driver
provides full acceleration and supports the following depths: 1, 4, 8,
15, 16, 24 and on the latest chipsets an 8+16 overlay mode. All visual types
are supported for depth 1, 4 and 8 and both TrueColor and DirectColor visuals
are supported where possible. Multi-head configurations are supported on
PCI or AGP buses.

The chips driver supports video processors
on most of the bus types currently available. The chipsets supported fall
into one of three architectural classes. A basic architecture, the WinGine
architecture and the newer HiQV architecture.

Color depths 1, 4 and 8 are supported on all chipsets, while
depths 15, 16 and 24 are supported only on the 65540, 65545, 65546 and
65548 chipsets. The driver is accelerated when used with the 65545, 65546
or 65548 chipsets, however the DirectColor visual is not available.

Wingine
Architecture

The supported chipsets are ct64200 and ct64300

Color depths
1, 4 and 8 are supported on both chipsets, while depths 15, 16 and 24 are
supported only on the 64300 chipsets. The driver is accelerated when used
with the 64300 chipsets, however the DirectColor visual is not available.

Color depths 1, 4, 8, 15, 16, 24 and 8+16
are supported on all chipsets. The DirectColor visual is supported on all
color depths except the 8+16 overlay mode. Full acceleration is supplied
for all chipsets.

Enable or disable combining the sync signals with the green signal. Default:
off.

Option "ShowCache" "boolean"

Enable or disable viewing offscreen memory.
Used for debugging only Default: off.

Option "18bitBus" "boolean"

Force
the driver to assume that the flat panel has an 18bit data bus. Default:
off.

Option "Crt2Memory" "integer"

In a dual-head mode (69030 only) this
option selects the amount of memory to set aside for the second head. If
not specified, half the memory is used. Default: off.

Option "DualRefresh"
"integer"

The 69030 supports independent refresh rates on its two display
channels. This mode of operations uses additional memory bandwidth and thus
limits the maximum colour depth and refresh rate that can be achieved,
and so is off by default. Using this option forces the use of an independent
refresh rate on the two screens. Default: off.
